Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber piston rod technology, specifically an adjustable support structure for automotive shock absorber piston rod. Background Technology

[0002] In the automotive industry, shock absorbers are key components that ensure vehicle driving comfort and stability. Their performance directly affects the overall vehicle handling experience and safety. The piston rod support structure of automotive shock absorbers needs to be flexibly adjusted according to different vehicle models, road conditions and load conditions to adapt to complex usage environments.

[0003] Currently, the piston rod support structure of existing automotive shock absorbers has certain limitations in practical applications. For example, some automotive shock absorbers cannot adjust the piston rod support structure, affecting applicability. At the same time, some support structures have complex adjustment methods, making it difficult to quickly adapt to different working conditions, resulting in low assembly and maintenance efficiency. During vehicle operation, due to factors such as road vibration, the piston rod is prone to displacement, affecting the working stability of the shock absorber.

[0004] According to the description of a piston rod for an automotive shock absorber published on the patent website (authorization announcement number: CN215890917U), the piston rod for the automotive shock absorber includes "first rod column, second rod column", etc., to achieve shock absorption.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] The piston rod of this car shock absorber uses a first rod and a second rod to achieve shock absorption. Although the piston rod can play a protective role during use, it cannot flexibly adjust its extension and retraction length within the cylinder to adapt to the shock absorber stroke requirements of different car models, road conditions, and loads, thus affecting its applicability and shock absorption effect. Therefore, this piston rod needs to be improved. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable support structure for the piston rod of an automotive shock absorber, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an adjustable support structure for a piston rod of an automotive shock absorber, comprising a first connecting support, an adjustment mechanism on the right side of the first connecting support, and a fixing mechanism on the inner side of the adjustment mechanism;

[0009] The adjusting mechanism includes a cylinder, which is fixedly connected to the right side of the first connecting support. A sealing seat is threadedly connected to the right side of the cylinder. A piston rod body is slidably connected inside the cylinder. A piston body is provided on the left side of the piston rod body. A sealing ring is sleeved around the piston body. A connecting seat is slidably connected to the right side of the piston rod body. A second connecting support is fixedly connected to the right side of the connecting seat. A limit frame is inserted into the front side of the connecting seat. A protective frame is fixedly connected to the right side of the limit frame. The protective frame is slidably connected to the periphery of the connecting seat. A fixed shaft is threadedly connected inside the limit frame.

[0010] Preferably, the right side of the protective frame is in contact with the right side of the connecting seat, and the right end of the protective frame is slidably connected to the outer periphery of the left end of the second connecting support. The rear side of the limiting frame penetrates the inside of the piston rod body, which facilitates further ensuring the stability between the connecting seat and the piston rod body through the protective frame.

[0011] Preferably, the limiting frame, the fixed shaft, and the protective frame are provided in two sets and are symmetrically distributed on the front and rear sides of the connecting seat. The fixed shaft passes through the inside of the two sets of limiting frames and also passes through the inside of the piston rod body. By providing two sets, the stability between the connecting seat and the piston rod body is ensured.

[0012] Preferably, the right side of the piston body is in contact with the left side of the piston rod body, and the piston body is slidably connected inside the cylinder, so that the piston body can play a buffering role by moving inside the cylinder.

[0013] Preferably, the piston rod body is slidably connected inside the sealing seat, which facilitates the sealing of the cylinder through the sealing seat.

[0014] Preferably, the fixing mechanism includes a limiting shaft, which is threadedly connected to the inside of the piston body. A fixing disc is fixedly connected to the left side of the limiting shaft, and the fixing disc is threadedly connected to the inside of the piston body. A circular disc is fixedly connected to the left side of the fixing disc.

[0015] Preferably, the right side of the limiting shaft extends through the inside of the piston rod body, the right side of the disc contacts the left side of the piston body, and the diameter of the disc is smaller than the diameter of the piston body, so as to ensure the stability between the piston body and the piston rod body through the limiting shaft and the fixing disc.

[0016] Compared with the prior art, this utility model provides an adjustable support structure for the piston rod of an automotive shock absorber, which has the following advantages:

[0017] 1. The adjustable support structure of the piston rod of this automotive shock absorber, through the set adjustment mechanism and the threaded connection design between the cylinder and the sealing seat, allows users to quickly assemble and seal the cylinder by rotating the sealing seat. The piston rod body is slidably connected inside the sealing seat and then inside the cylinder. The sealing seat is then threadedly connected to the right side of the cylinder, completing the assembly. Adjusting the position of the right end of the piston rod body inside the connecting seat allows for flexible adjustment of the piston rod body's extension length within the cylinder, adapting to different vehicle models, road conditions, and load requirements for the shock absorber's stroke. Combined with the limiting structure of the limit bracket, fixed shaft, and protective bracket, [the system achieves this]. After adjustment, the piston rod body and the connecting seat can be securely locked together, effectively preventing piston rod displacement caused by vibration during vehicle operation. This ensures that the shock absorber always remains in the preset working state, providing stable and reliable shock absorption support for the vehicle. The sealing ring sleeved around the piston body fits tightly against the inner wall of the cylinder, effectively preventing hydraulic oil leakage from the cylinder and ensuring the integrity and sealing of the shock absorber's hydraulic system. This maintains the normal working performance of the shock absorber. The design of the protective frame further ensures the stability between the piston rod body and the connecting seat, extends the service life of key components of the shock absorber, and reduces maintenance costs and frequency.

[0018] 2. The adjustable support structure of the piston rod of this automotive shock absorber, through the combination of a fixed mechanism, a limiting shaft, a fixed disc, and a disc, and a threaded connection, can quickly fix and disassemble the piston body and the piston rod body, simplifying the installation and maintenance process, improving assembly and maintenance efficiency, and reducing operating difficulty and time costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-6 This utility model provides a technical solution: an adjustable support structure for a piston rod of an automobile shock absorber, including a first connecting support 1, an adjustment mechanism 2 on the right side of the first connecting support 1, and a fixing mechanism 3 on the inner side of the adjustment mechanism 2;

[0032] The adjusting mechanism 2 includes a cylinder 21, which is fixedly connected to the right side of the first connecting support 1. A sealing seat 22 is threadedly connected to the right side of the cylinder 21. A piston rod body 23 is slidably connected inside the cylinder 21. A piston body 24 is provided on the left side of the piston rod body 23. A sealing ring 25 is sleeved around the piston body 24. A connecting seat 26 is slidably connected to the outer periphery of the right end of the piston rod body 23. A second connecting support 27 is fixedly connected to the right side of the connecting seat 26. A limit frame 28 is inserted into the front side of the connecting seat 26. A protective frame 291 is fixedly connected to the right side of the limit frame 28. The protective frame 291 is slidably connected to the outer periphery of the connecting seat 26. A fixed shaft 29 is threadedly connected inside the limit frame 28.

[0033] The right side of the inner side of the protective frame 291 is in contact with the right side of the connecting seat 26, and the right end of the protective frame 291 is slidably connected to the outer periphery of the left end of the second connecting support 27. The rear side of the limiting frame 28 penetrates the interior of the piston rod body 23, so that the stability between the connecting seat 26 and the piston rod body 23 can be further guaranteed by the protective frame 291.

[0034] Two sets of limiting brackets 28, fixed shafts 29, and protective brackets 291 are provided and symmetrically distributed on the front and rear sides of the connecting seat 26. The fixed shaft 29 passes through the interior of the two sets of limiting brackets 28 and also passes through the interior of the piston rod body 23. By setting two sets, the stability between the connecting seat 26 and the piston rod body 23 is ensured.

[0035] The right side of the piston body 24 is in contact with the left side of the piston rod body 23. The piston body 24 is slidably connected inside the cylinder 21, which facilitates the movement of the piston body 24 inside the cylinder 21 to achieve a buffering effect. The piston rod body 23 is slidably connected inside the sealing seat 22, which facilitates the sealing of the cylinder 21 through the sealing seat 22.

[0036] Example 2

[0037] Please see Figure 1-6 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes a limiting shaft 31, which is threadedly connected to the inside of the piston body 24. A fixing disk 32 is fixedly connected to the left side of the limiting shaft 31, which is threadedly connected to the inside of the piston body 24. A disc 33 is fixedly connected to the left side of the fixing disk 32.

[0038] The right side of the limiting shaft 31 extends through the inside of the piston rod body 23, and the right side of the disc 33 contacts the left side of the piston body 24. The diameter of the disc 33 is smaller than the diameter of the piston body 24, which facilitates the stability between the piston body 24 and the piston rod body 23 through the limiting shaft 31 and the fixed disc 32.

[0039] In actual operation, when this device is used, the threaded connection design between the cylinder 21 and the sealing seat 22 allows the user to quickly assemble and seal the cylinder 21 by rotating the sealing seat 22, slide the piston rod body 23 into the sealing seat 22, and make the right side of the piston body 24 and the left side of the piston rod body 23 contact each other. The limiting shaft 31 is threaded into the piston body 24 and the piston rod body 23, and drives the fixing disk 32 to be threaded into the piston body 24, so that the right side of the disk 33 and the left side of the piston body 24 contact each other. This allows for quick fixing and disassembly of the piston body 24 and the piston rod body 23, while ensuring the stability between the piston body 24 and the piston rod body 23.

[0040] By having the piston rod body 23 drive the piston body 24 to slide and connect inside the cylinder 21, the sealing seat 22 can be threaded to the right side of the cylinder 21 to complete the assembly work.

[0041] The adjustment of the position of the right end of the piston rod body 23 inside the connecting seat 26 can flexibly adjust the extension length of the piston rod body 23 inside the cylinder 21 to adapt to the requirements of different vehicle models, road conditions and loads on the shock absorber stroke. After the adjustment is completed, the two sets of limit brackets 28 can be inserted into the front and rear sides of the connecting seat 26 respectively, and pass through the inside of the piston rod body 23. At the same time, the limit shaft 31 passes through the two sets of limit brackets 28 and the piston rod body 23 to ensure the stability between the three.

[0042] After adjustment, the piston rod body 23 and the connecting seat 26 can be securely locked to effectively prevent piston rod displacement caused by vibration during vehicle operation, ensuring that the shock absorber always maintains the preset working state and provides stable and reliable shock absorption support for the vehicle. The sealing ring 25 sleeved around the piston body 24 fits tightly with the inner wall of the cylinder 21, which can effectively prevent hydraulic oil leakage in the cylinder 21, ensure the integrity and sealing of the shock absorber hydraulic system, and thus maintain the normal working performance of the shock absorber. The design of the protective frame 291 further ensures the stability between the piston rod body 23 and the connecting seat 26, extends the service life of key components of the shock absorber, and reduces maintenance costs and frequency.

[0043] The adjustable design and robust fixing method can adapt to complex vibration environments under different working conditions, enhance the comfort and stability of the vehicle during driving, and improve the handling performance and safety of the whole vehicle. The shock absorber used in this case is a shock absorber with hydraulic oil as the buffer medium.
